spring aop 实现方法执行时间监控

1.在Mycelipse 中创建maven 工程

2.在pom中添加spring依赖

   主要是spring包，cglib包，log4j包等，详细查看pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.cyou</groupId><artifactId>performence-monitor</artifactId><version>1.0-SNAPSHOT</version><packaging>jar</packaging><name>performence-monitor</name><url>http://maven.apache.org</url><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><commons-lang.version>2.6</commons-lang.version><spring.version>3.2.4.RELEASE</spring.version><aspectj.version>1.7.3</aspectj.version><cglib.version>3.0</cglib.version><slf4j.version>1.7.7</slf4j.version><log4j.version>1.2.17</log4j.version><junit.version>3.8.1</junit.version><slf4j.version>1.7.7</slf4j.version></properties><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>${junit.version}</version><scope>test</scope></dependency><dependency><groupId>commons-lang</groupId><artifactId>commons-lang</artifactId><version>${commons-lang.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.aspectj</groupId><artifactId>aspectjtools</artifactId><version>${aspectj.version}</version></dependency><dependency><groupId>cglib</groupId><artifactId>cglib</artifactId><version>${cglib.version}</version><scope>runtime</scope></dependency><dependency><groupId>org.slf4j</groupId><artifactId>log4j-over-slf4j</artifactId><version>${slf4j.version}</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>jcl-over-slf4j</artifactId><version>${slf4j.version}</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>jul-to-slf4j</artifactId><version>${slf4j.version}</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>${slf4j.version}</version></dependency></dependencies><build><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.1</version><configuration><target>1.6</target><source>1.6</source><encoding>utf-8</encoding><fork>true</fork><meminitial>128m</meminitial><maxmem>512m</maxmem><compilerArguments><verbose /></compilerArguments></configuration></plugin></plugins></build></project>

3.在resources创建applicationContext-aop.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"xmlns:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="          http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd          http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd        http://www.springframework.org/schema/context           http://www.springframework.org/schema/context/spring-context-3.0.xsd        ">        <context:component-scan base-package="com.henry" /><aop:aspectj-autoproxy proxy-target-class="true"/></beans>

4.创建aop切面类

/* * 文 件 名:  PerformenceMonitor.java * 描    述:  <描述> * 修 改 人:  Administrator * 修改时间:  2014-10-22 * 跟踪单号:  <跟踪单号> * 修改单号:  <修改单号> * 修改内容:  <修改内容> */package com.henry.aop;import org.aspectj.lang.ProceedingJoinPoint;import org.aspectj.lang.annotation.Around;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Pointcut;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.stereotype.Component;/** * 监控service接口的运行时间 * <功能详细描述> *  * @author  Administrator * @version  [版本号, 2014-10-22] * @see  [相关类/方法] * @since  [产品/模块版本] */@Aspect@Componentpublic class PerformenceMonitor {private static final Logger logger = LoggerFactory.getLogger("monitor");/** * 监控com.henry.advertising.web.service包及其子包的所有public方法 * <功能详细描述> * @see [类、类#方法、类#成员] */    @Pointcut("execution(* com.henry.advertising.web.service..*.*(..))")      private void pointCutMethod() {      }   //声明环绕通知      @Around("pointCutMethod()")      public Object doAround(ProceedingJoinPoint pjp) throws Throwable {          long begin = System.nanoTime();        Object o = pjp.proceed();          long end = System.nanoTime();        logger.debug("{}:{}",pjp.getTarget().getClass()+"."+pjp.getSignature().getName(),(end-begin)/1000000);        return o;      }  }

5.然后运行maven clean install 打包

这样就生成了一个能够监控方法执行时间的监控。可以对切面类的pointcut重新进行正则，这样就能写出一个通用的监控类

6.在别的工程中引用该jar包，实现监控

  6.1在工程中引入改jar包

        <dependency><groupId>com.cyou</groupId><artifactId>performence-monitor</artifactId><version>1.0-SNAPSHOT</version></dependency>

6.2在工程的application.xml中引入该jar包的配置文件

<import resource="classpath:/applicationContext-aop.xml"/>

6.3在工程的log4j中配置日志文件路径

   要注意顺序

  <appender name="performence.monitor.file" class="org.apache.log4j.DailyRollingFileAppender">    <param name="file" value="${catalina.home}/logs/performece" />    <param name="Append" value="true" />    <param name="encoding" value="UTF-8" />    <layout class="org.apache.log4j.PatternLayout">      <param name="ConversionPattern" value="%d{yyyy-MM-dd HH:mm:ss,SSS} %r %-5p [%F:%L] : %m%n" />    </layout>  </appender>  <logger name="monitor">  <level value="debug" />  <appender-ref ref="stdout" />    <appender-ref ref="performence.monitor.file" />  </logger>

这样，在启动这个工程的时候，监控模块就能把所拦截的方法执行时间信息打印到指定的文件中，然后供开发人员分析

结果如下:
